Strong storms hit the lower 48 states yesterday, producing over 220 reports of severe weather from the Plains to the Southeast.

Eighteen tornadoes were reported, all of them from the Dallas-Fort Worth area into Northeastern Texas. Baseball-size hail caused damage to airplanes at the Dallas-Fort Worth International Airport, forcing hundreds of cancellations even through Wednesday.

And the threat for more is not over yet…

There’s another chance for severe thunderstorms from Louisiana up into Eastern Kansas, and east to Virginia.

A tornado warning means that a tornado can be on the ground shortly, if not already, and you should seek shelter immediately, preferably in a basement.

If you do not have a basement, try to stay away from windows, and go to an interior room, on the lowest floor of your home.

The weather will remain relatively calm in the Dallas area over the next few days, which should help clean up efforts.
